Noise information

Noise emission values determined according to

EN 62841‑3‑6

.

Typically the A-weighted noise level of the power tool is:
Sound pressure level 

96

 dB(A); sound power level

110

 dB(A). Uncertainty K=

3

 dB.

Wear hearing protection

The noise emission value given in these instructions has
been measured in accordance with a standardised measur-
ing procedure and may be used to compare power tools. It
may also be used for a preliminary estimation of noise emis-
sions.
The noise emission value given represents the main applica-
tions of the power tool. However, if the power tool is used
for other applications, with different application tools or is
poorly maintained, the noise emission value may differ. This
may significantly increase noise emissions over the total
working period.
To estimate noise emissions accurately, the times when the
tool is switched off, or when it is running but not actually be-
ing used, should also be taken into account. This may signi-
ficantly reduce noise emissions over the total working
period.

Assembly

u

Pull the plug out of the socket before carrying out any
work on the power tool.

Assembling the drill stand

Carrying handle

Before initial commissioning, screw the drill stand carrying
handle 

(11)

 firmly in place on the drill column using the

screws 

(12)

. In doing so, position the cap of the carrying

handle so that it closes in line with the drill column.

Star handle

Screw the three handlebars of the star handle 

(15)

 all the

way into the central hub of the star handle.
The star handle 

(15)

 serves both as the feed crank during

drilling and as a means of loosening or tightening screws on
the drill stand.
To drill, push the star handle all the way to the left or right
(as required) and onto the feed pinion 

(26)

. Pull the star

handle off firmly to remove it.

Feed lock with locking brake

Lock the feed when performing any work on the drill stand,
during breaks and when not using the drill stand. Do this by
engaging the locking brake 

(16)

.

To drill, loosen the locking brake 

(16)

 until the star

handle 

(15)

 is easy to move. When doing so, hold the star

handle in place to prevent the power tool from sliding down
in an uncontrolled manner.

Attaching the carrying handle to the power tool

Before initial commissioning, screw the carrying handle 

(9)

firmly in place on the power tool using the screws 

(10)

.

Inserting the power tool (see figures A–B)

Ensure that the locking brake 

(16)

 is on.

The drill holder 

(27)

 has a recess on the right-hand side.

When placing the machine adapter 

(25)

 onto the power tool,

ensure that the flange on the machine adapter also sits on
the right as shown in the diagram 

B

.

Position the machine adapter 

(25)

 on the power tool so that

the feather keys 

(24)

 of the machine adapter click into the

corresponding recesses of the power tool. Insert the four
screws 

(23)

 of the machine adapter and tighten them using

a hex key (size 6 mm).
Loosen the eccentric bolt 

(14)

 using the star handle 

(15)

and pull it as far as possible out of the drill holder 

(27)

. Use

the machine adapter 

(25)

 to hang the power tool in the drill

holder so that the lower lip of the machine adapter sits be-
hind the lower bolt of the drill holder 

➊

.

Hinge the power tool into the drill holder 

➋

 and reinsert the

eccentric bolt 

(14)

. Tighten the eccentric bolt using the star

handle 

(15)

.

Slide the star handle 

(15)

 to the right or left and onto the

feed pinion 

(26)

 in order to drill.
